Ternary Halides of the A3MX6 Type. VI. Ternary Chlorides of the Rare-Earth Elements with Lithium, Li3MCl6 (M ? Tb? Lu, Y, Sc): Synthesis, Crystal Structures, and Ionic Motion Single crystal X-ray studies on the ternary chlorides Li3ErCl6, Li3YbCl6 and Li3ScCl6 show that they crystallize in three different structure types. Li3ErCl6 (trigonal, P3 ml, Z = 3, a = 1117.7(2); c = 603.6(2) pm; the chlorides with M ? Tb? Tm, Y are isotypic) and Li3YbCl6 (orthorhombic, Pnma, Z = 4, a = 1286.6(1); b = 1113.2(1); c = 602.95(8) pm; Li3LuCl6 is isotypic) have very similar structures that may be derived from hexagonal closest packings of chloride ions with the cations occupying octahedral holes in part statistically. Li3ScCl6 (monoclinic, C2/m, Z = 2, a = 639.8(1); b = 1104.0(2); c = 639,1(1) pm; β = 109.89(1)°) crystallizes isotypic with Na3GdI6 and Li3ErBr6, structures that may be derived from a cubic closes packings of anions. The ionic movement in Li3YCl6 and Li3YbCl6 has been investigated by impedance and 7Li-NMR spectroscopy. 相似文献

Syntheses and Characterizations of the First Tris and Tetrakis(trifluoromethyl) Palladates(II) and Platinates(II), [M(CF3)3(PPh3)]— and [M(CF3)4]2— (M = Pd, Pt) Tris(trifluoromethyl)(triphenylphosphino)palladate(II) and platinate(II), [M(CF3)3PPh3]—, and the tetrakis(trifluoromethyl)metallates, [M(CF3)4]2— (M = Pd, Pt), are prepared from the reactions of [MCl2(PPh3)2] and Me3SiCF3 / [Me4N]F or [I(CF3)2]— salts in good yields. [Me4N][M(CF3)3(PPh3)] crystallize isotypically in the orthorhombic space group Pnma (no. 62) with Z = 4. The NMR spectra of the new compounds are described. 相似文献

In the present comment it will be outlined that the recently published perchlorate [Zn(OH)(μ‐ClO4)(H2O)3]2 is in fact the well known sulfate ZnSO4·4H2O. The assumption is supported by both bond lengths considerations and structural characteristics. 相似文献

The S6O192? ion was obtained both as rubidium and ammonium salt from the reaction of the respective sulfate with SO3. It is the largest polysulfate ion known to date and exhibits a chain of six vertex‐connected [SO4] tetrahedra. The unique compound was comprehensively characterized and the bonding within the anion was elucidated by theoretical investigations. 相似文献

For the first time tetravalent palladium is detected, coordinated exclusively by simple oxoanions. Stabilization was achieved by formation of the [Pd(S2O7)3]2? complex in which three chelating disulfate groups surround the metal atom. The salt K2[Pd(S2O7)3] could only be obtained if the reaction of K2[PdCl6] and neat SO3 was performed in the presence of XeF2. 相似文献

The reaction of Eu2O3 with fuming nitric acid, trifluormethanesulfonic acid, and its anhydride in torch‐sealed glass ampoules at 120 °C gave the europium compound (NO)5[Eu(O3SCF3)8] (orthorhombic, Fddd, Z=16, a=1932.69(4), b=2878.44(7), c=2955.12(7) pm, V=16439.7(7) Å3). The compound exhibits the [Eu(O3SCF3)8]5? anion showing for the first time a lanthanide ion that is exclusively coordinated by eight triflate anions. The anion has been further investigated by DFT calculations, which also allowed clear assignment of the vibrational spectra. Moreover, magnetochemical and luminescence measurements gave additional insight into the properties of this complex. The luminescence spectra revealed that the Eu3+ ions are in a pseudo D4d symmetric environment. 相似文献
